Thanks for the hint but, unless I miss something, that only shows the 
equivalent of what I am doing when using pure opengl to get the opengl 
frame:

image = glReadPixelsub(0,0, self.width(), self.height(), GL_RGBA, 
GL_UNSIGNED_BYTE)

What I need is to be able to export a set of images as a "portable" 
animation and, if possible, from within my own python and qt program.
